Answer:
The leaf. Unlike animals, plants do not have specialised excretory organs. Excess carbon dioxide and oxygen are excreted from the plant through the stomata in the leaves.During day time, oxygen is produced in the leaves. This is because photosynthesis occurs during the day. So leaves use some of this oxygen for respiration and rest of it is diffused out in the air. The carbon dioxide produced during respiration in the leaves is also used up in photosynthesis.
